51 Star Flag of the United States of America (USA) Glass

This design features an artistic representation of a potential American flag with 51 stars, which could be used if a 51st U.S. state were ever to join the United States of America. The design is in the public domain. Voters in the District of Columbia and Puerto Rico have both voted for statehood in referendums. However, their potential admission to the Union requires congressional approval. American Samoa, Guam, the Northern Mariana Islands and the United States Virgin Islands are also U.S. territories and could potentially become U.S. states in the future.
